Waynesville, MO Building Setbacks & Zoning: Lot Coverage Limits (2026)

Waynesville does not set one citywide lot coverage percentage; instead the zoning ordinance repeats a 40 percent ceiling in the districts where it applies rather than leaving coverage unregulated. Section 405.360, titled Percentage Lot Coverage, governs the C-1 Neighborhood Commercial District and states that all buildings, including accessory buildings, cannot cover more than 40 percent of the lot. Section 405.220 applies the same 40 percent limit to multi-family dwellings in the R-3 Multi-Family Residential District, measuring the combined footprint of the main building and any accessory buildings against the total lot area; that same section separately requires at least 20 percent of an R-3 multi-family lot to remain open space.

Section 405.322 sets an identical 40 percent lot coverage cap for a single-family dwelling in the R-CS1 Container and Small Homes Residential District, again counting the main structure together with any accessory buildings. The Zoning Administrator and Building Official review a site plan against the applicable coverage limit before issuing a building permit under Section 405.740, and property owners who need relief from the percentage can apply to the Board of Adjustment created under Section 405.760. Because the R-1, R-2 and A-1 district regulations in Sections 405.130, 405.160 and 405.190 set only minimum yard and lot-area numbers without a separate percentage, a homeowner in those districts should confirm coverage against the applicable front, side and rear yard setbacks rather than a stated percentage.
